A specialized cell that only holds one prisoner that has been sentenced to solitary confinement. Prisoners who do not respect the prison rules are brought here for a specified amount of time based on your Policy, or they can be sent there by you manually for whatever reason. A solitary cell can be smaller than a normal cell, allowing you to fit them into otherwise wasted spaces.

Solitary builds up Suppression very quickly and will fully suppress a prisoner after 2 hours and 15 minutes in-game. With Warden Rita this time is halved. Once released, the prisoner will lose suppression very slowly.

Other than Cells, Dormitories and Holding Cells, Solitary Cells do not require any equipment like beds or toilets. They may of course contain such objects anyway, to avoid prisoners' needs rising during solitary. The only need that will be addressed otherwise will be the food need, as meals will be brought to solitary cells by guards to prevent the prisoners from starving.

The only way to recruit Confidential Informants is approaching prisoners currently locked in solitary, as some of them will be willing to turn snitch in exchange for early release from confinement. Click on a prisoner in solitary and go to the 'Experience' tab and there is a chance he will have the option "Recruit Informant" available.

Building solitary cells will not increase your prison's capacity (and thus its valuation in the according Report) as normal cells and dormitories do, and holding cells if they are containing beds. Also, solitary cells won't get a cell grading like normal cells and dormitories.
